Problems solved by technology

Among them, glasses-type 3D technology is gradually at a disadvantage due to its narrow viewing angle, expensive glasses, and small application range; glasses-free 3D technology has gradually become popular, but the existing glasses-free 3D technology requires users to be in a specific position to watch The best 3D display effect cannot be automatically adjusted according to the user's distance from the display to ensure the best 3D display effect. Therefore, if the user is not in a specific position, he cannot see the real three-dimensional picture, and the three-dimensional image effect is not ideal. , and the existing naked-eye technology requires a higher minimum refresh rate of the display (120Hz), and the cost of a display with a high refresh rate is relatively high, which is not easy to promote and use

Embodiment 1

[0070] The invention provides a naked-eye 3D image display device, which can be realized by more than two display screens. The embodiment of the present invention takes two display screens as an example to provide a naked-eye 3D image display device, such as figure 1 As shown, the device includes:

[0071] 2D / 3D converter, depth of field processing control module, infrared sensing module and at least two display screens.

[0072] This embodiment takes two display screens as an example to introduce in detail, that is, the display device includes a first display screen and a second display screen, the first display screen and the second display screen are overlapped, and the second display screen is larger than the first display screen. screen away from the user.

[0073] The 2D / 3D converter is used to convert ordinary 2D signals into 3D stereo signals. The basic principle of the 2D to 3D conversion function is to analyze the 2D scene, outline and highlight the close-range ima...

Embodiment 2

[0082] An embodiment of the present invention provides a naked-eye 3D image display device. The modules included in the display device in this embodiment are the same as those in the first embodiment.

[0083] Further, the display device also includes a third display screen. While increasing the number of display screens, the overall thickness of the display device is also increased, which enhances the effect of 3D stereoscopic display and makes the effect of 3D stereoscopic display more realistic and ideal.

[0084] Further, the depth-of-field processing control module is used to calculate and separate the 3D stereo signal into a first signal, a second signal, and a third signal, and perform depth-of-field processing on the first signal, second signal, and third signal according to the infrared sensing distance signal. processing, and send the depth-of-field-processed first signal, second signal and third signal to the first display screen, the second display screen and the t...

Embodiment 3

[0089] An embodiment of the present invention provides a naked-eye 3D image display method. In this embodiment, a display device having two display screens is used as an example to describe in detail, that is, the display device includes a first display screen and a second display screen.

[0090] Such as Figure 4 As shown, the display method includes:

[0091] In step 101, the 2D / 3D converter converts ordinary 2D signals into 3D stereoscopic signals.

[0092] The basic principle of the 2D to 3D function is to analyze the 2D scene, outline and highlight the close-range image in the scene, and at the same time put the distant view image in the back, for example, people, etc. in the front, background environment and objects in the back; further In this way, the front part of the same object is fronted, and the rear part is reared, so that the 2D image can be transformed into a 3D effect in real time.

[0093] Step 102, the depth of field processing control module calculates and...

Abstract

The embodiment of the invention discloses a naked-eye 3D image display device and a naked-eye 3D image display method. The invention is characterized in that the depth-of-field processing is carried out on a 3D image according to the distance of a user away from a display screen, 3D stereoscopic display is carried out, and simultaneously, the lowest refresh frequency required by a display device is reduced when the display of the 3D image is implemented, and the implementation cost is reduced. The display device comprises a 2D / 3D converter, a depth-of-field processing control module, an infrared sensing module and a display screen. The invention is applied to the field of 3D display.

Description

technical field [0001] The invention relates to the technical field of 3D stereoscopic display, in particular to a naked-eye 3D image display device and method. Background technique [0002] Displays have always been the most frequently contacted electronic devices with people. With the rapid development of science, displays have developed from a single black and white display to a colorful high-quality display. 3D (Three Dimension, 3D for short) stereoscopic display technology In addition to providing people with general images and colors, it also provides people with a further three-dimensional feeling of space. [0003] The reason why people can experience stereoscopic vision is that the human eyes are side by side with about 6-7 centimeters apart, so the image seen by the left eye and the image seen by the right eye will be slightly different , this difference is called parallax, the brain will interpret the parallax of the eyes and use it to judge the distance of objec...
